GEORGE O. SANDERSON, OF BOSTON, MASSACHUSETTS.

PORTABLE FURNACE FOR TINNERS.

SPECIFICATION forming part of Letters Patent No. 339,934, dated April 13, 1886.

Application filed April 24, 1885. Serial No.163,289. (No model.)

To all whom, it may concern.-

Be it known that I, GEORGE O. SANDERSON, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Portable Furnaces for Tinners and Plumbers Use, of which the following is a specification.

The object of my invention is to produce a compact and portable furnace adapted for heatingsoldering-irons and for melting solder, and furnishing a convenient furnace for the tinner and plumber.

The invention consists in a peculiar construction, hereinafter fully described, and set forth in the claims, whereby the furnace is equally adapted for use both by tinners and plumbers, whereas separate furnaces have heretofore been required for such uses.

Referring to the accompanying drawings, Figure 1 is a front elevation of the furnace. Fig. 2 is a top view with the covers removed. Fig. 3 is a vertical transverse section of Fig. 1;and Fig. 4 is avertical longitudinal section, the upper cover and pot being removed.

A is a stand, which may be of any suitable size or shape. To the upper part of the stand A is secured the furnace or chamber B,which is contracted at its lower end, and having its sides flaring upward and outward, as shown in Figs. 1 and 3.

At the front end of the chamber Bis an opening, 0, through which the soldering-irons are inserted.

At the rear of the chamber B is a V-shaped offset, B B, the lower end of which serves as a support for the inner ends of the soldering- The V shape of the support serves to keep the iron at the center of the furnace.

At one side of the chamber B is a hole, I), through which the flame for heating the furnace is caused to pass from a perforated pipe, I, to be connected with any suitable hydrocarbon apparatus.

I propose to use the apparatus described in Patent No. 284,365, to Wellington, September 4, 1883.

On the top of the furnace or chamber B is fitted a rectangular plate, O, having acircular opening, in which is fitted a cover, D, having a cavity, (2, for the insertion of a lifter.

E is a bail hinged to the upper sides of the center of the furnace.

On each side of the front end of the furnace is a projection or shoulder, F, which projections serve as a support for the bail, and are so arranged that when the bail is down, as shown in Figs. 4 and 1, the front end will be on a level, or about so, with the lower end of the opening 0, and thus serve as a support for the handles or outer ends of the solderingirons.

e is a cross-bar in the lower part of the fur nace, for supporting the soldering-irons. k is an opening at the bottom of the chamber B. A gas-jet may be introduced under the chamber B, if desirable.

Then the furnace is used for melting solder, the circular cover D is removed, and a melt ing-pot, H, Fig. 3, is set in the opening of the plate 0. Around the circular edge of the plate 0 are projections a a, as shown in Fig. 2, against which the pot H bears, so as to allow the heat to-pass up in the openings be tween the projections and around the pot. Over the pot H is placed a cover, G, the lower ends of which rest upon the plate 0, and is provided with a handle, G. At the upper part of the cover are holes 9 g.

The cover G serves to concentrate the heat upon and around the melting-pot, and the holes 9 tend to promote a free circulation of the heat.

\Vhat I claim as my invention is 1. In a portable furnace, the combination of the chamber B, the perforated plate 0, the pot H, and cover G, provided with holesgg, as and for the purpose set forth.

2. The chamber or furnace B, provided with the supports F F, in combination with the bail E, for supporting the outer ends of the soldering-irons, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE O. SANDERSON.
